The howto that you followed is incompatible with ISPConfig 2. ISPConfig 2 uses a linux system user setup to manage email accounts while you used a guide for apostfix virtual user setup. So your setup can not work with ispconfig 2 and recompiling postfix is not required for ISPConfig 2.

You wil have tp decide what you want? A virtual user setup, then follow the guide above and dont install ispconfig2. If you want to use ispconfig 2, then dont use the guide above and instaed ise a perfect setup guide for ispconfig 2.

If you want to use a virtual user setup for email with a controlpanel, then you might want to use ispconfig 3 and this guide here instead:

I'm looking for virtual users and domains in a mysql database using maildir format. I don't understand why the guide would be incompatible. I'm running CentOS-6. Did I miss something?

Personally, I dislike control panels as they do nothing but lead to yet another attack vector. Assuming someone did get into my server once I've locked it down, I'd like to assume they're too dumb to know enough SQL. (security through stupidity). Half the crackers out there are script kiddies (I'm guessing).

You posted here in the forum of the controlpanel "ISPConfig 2" and not the generalLinux forum. So everyone has to assume that you use ispconfig 2, especially as you put this in the subject of your post too.

Is there any resolution to this error when compiling postfix on linode kernels? I have been following the correct tutorial that falko has pointed out and have never install ISPconfig (The title of the thread it incorrect). I will gladly start a new thread or post and configs that may be needed.
